band on the screen. When the interference is destructive, this is shown as a
band on the screen.
Answer: When the interference is constructive, this is shown as a bright band on the screen. When the interference is destructive, this is shown as a dark band on the screen.
Explanation: edge 2021
Answer:Bright and Dark
Explanation:
Answer:
402m
Explanation:
We can solve this easily by using the free fall formula:
On both cases the final velocity will be 0m/s (maximum height), so we have:
We know that the velocity the person imparts to the ball will be the same either on Earth or on the Moon, so we write for both cases:
Which means
So we get (taking into account that gravity on earth is 6 times gravity on the Moon):
c. the gearbox.
b. the shaft.
d. a brush.
Answer:
a. the rotor
Explanation:
A commutator is a rotary electric switch that periodically changes the direction of the current between the rotor and the external circuit. In a motor provides energy to the rotor. It consists of a cylinder composed of multiple metal contact segments on the rotor.
Part A
In this experiment, you will place the container in the freezer. What do you think will happen?
Hypothesis: When the container with the balloon and plaster of Paris is placed in the freezer, the water inside the balloon will freeze and expand as it turns into ice. As the water freezes, it will exert pressure on the plaster, causing the plaster to crack or deform. The extent of cracking or deformation may depend on the strength and thickness of the plaster.
Part B of the experiment would typically involve conducting the experiment and observing the actual outcome to confirm or reject the hypothesis.
b. False
